Problem installing on SunOS 5.7 (Solaris 7)

["Cuccio Jr., Emilio (Chip)" <ChipCuccio fairisaac com>]

Greetings,
I am attempting to install Stronghold 4 on a SunOS 5.7 (Solaris 7)
server, and at the end of the installation (when it attempts to
start the server), I receive the following error:

     "An error occurred during installation.                 
      The error message is:
      Command "/opt/sh4/bin/start-server" returned error status 256
      This occurred while processing configuration file
      /opt/sh4/conf/.configure/.configure-trailer line 20"

After looking closer at my terminal, I noticed the following
diagnostic error message (after the installation aborts):

     "Ouch! ap_mm_create(1048576, "/opt/sh4/var/httpd.mm.2600") failed
      Error: MM: mm:core: failed to memory map anonymous area (Bad file
      number): OS: No such file or directory
      Server could not be started"

This machine presently runs Stronghold 3 with no issues.

What is the problem here? I am grateful for any assistance.
Thanks...
